In this set of cards the remarkable wildlife photographs of Art Wolfe are accompanied by intriguing facts about each animal portrayed, from Toco toucans that fly into people's homes and tease their pets to orangutans who construct a new sleeping platform every night, and crocodiles who swallow stones for ballast. Not much bigger than a pack of playing cards, this deck contains four dozen attractively decorated cards with individual entries. Use them as flash cards, or for impromptu trivia and quiz games, or simply read them as an unbound book.
